Abstract

A process has been developed to detoxify the waste magnesia-chromia bricks containing sexivalent chromium and recover valuable materials with arc plasma treatment. Especially magnesium and chromium, which are the major compounds of the waste bricks, could be separately recovered by carbothermic reduction with addition of iron. From the viewpoint of environmental protection and saving resources, such recovery processes are expected to be commercialized.
